Explanation

The statement 'EJB tier does not host system-level services... they are hosted on the EIS tier' is NOT true. The EJB container (within EJB tier) actually PROVIDES system-level services like transaction management, security, concurrency control, pooling, and lifecycle management. EIS tier handles enterprise information systems like databases and legacy systems.
